Archerbush
Archerbushes have sickly looking green leaves, stunted trunks, and thorny brown branches. Grow in scrubby mountainous regions, either solitarily or in small clusters. These carnivorous plants attack prey by shooting a spray of several small thorns at their victims (1d4 DMG/spray). The range is approximately 20', and each bush can fire up to three times per day. An archerbush can uproot itself to move slowly toward prey. The trunk of an archer bush looks like a 3' tall gnarled bush or pile of leaves, but a maw lined with sharp teeth can be seen between the "roots."
Encountered by Qrurr outside the Hall of Elements.
